In the blood

Suzie Fewings is a keen family history researcher. She's delighted when she discovers an ancestor with the same name as her teenage son. But what she finds out about the seventeenth-century Thomas casts a darker shadow than she expected. When her own Tom's girlfriend is found dead in mysterious circumstances, Suzie finds it hard to suppress her growing fears that Tom has inherited more than a name from his predecessor.--From publisher's description.
